Specification of Letters Patent.

Patented Aug. 14, 191?.

Application filed October 2, 1916. Serial No. 123,388.

To all whom it may concern:

Be it known that I, PAUL L. Gnnn, a citizen of the United States, and a resident of San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Self- Generating Heating-Torches, of which the following is a specification.

My invention relates to improvement in self generating heating torch; and the objects of my invention are:

First, to provide a self generating heating torch, that the feed hose thereof may be attached to a pressure tank having oil under pressure.

Second, to provide a self generating heating torch that may be used for brazing or preheating purposes, with a view to maintaining the heating efliciency, and producing a perfect combustion. V

The main object of the present invention is to provide a self generating heating torch for general heating purposes that may be light and durable, and one in which the carbon forming therein may be quickly removed therefrom, and one in which the fiame can be governed as required, and one in which the air and generated gas mingle together in the combustion chamber.

This invention in the preferred form of details will be described in the following specification, reference being had to the accompanying drawings, in which:

Figure 1 is a longitudinal section of my self generating heating torch, showing valves and pipes leading to and from generating chamber with needle valve in position in needle valve seat.

Fig. 2 is an end view of the generating heating torch showing needle opening in needle valve seat, and main inner and outer opening in combustion chamber.

Fig. 3 is a longitudinal side view of my self generating heating torch assembled with generating cup attached.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring now more particularly to the drawings; 1 is the outside casing of my self generating heating torch, having flat walls, said walls being flat greatly increase the amount of heating surface in the generating and combustion chambers; 2 is the boss projection which is an integral part of said cas- I ing 1, through which fuel oil enters under pressure from a pressure tank not shown through hose 3, and the amount required is regulated by fuel oil intake valve 4, said hose 3 being connected to one end of valve 4 by union coupling 5, the other end of said valve 4 being connected to coupling 6 by threaded portion 7, said coupling 6 being connected to pipe 8 by threaded portion 9, said pipe 8 being connected to boss projection 2 by threaded portion 10, fuel oil being delivered under pressure through opening 11 in casing 1 as the arrow points to generating chamber 12, where said fuel oil is generated into gas and is delivered from said generating chamber 12 through opening 13, to pipe 14:, as the arrow points, said pipe 14: connecting with boss projection 15 which is an integral part of easing 1 by threaded portion 16. On the outer end of said pipe 14, is connected a T coupling 17 by threaded portion 18; at the outer end of said T coupling 17 is connected plug 19 by threaded portion 20, said plug 19 being for the purpose of cleaning out any carbon that may accumulate in said pipe 14. Connected to said T coupling 17, by threaded portion 21 is needle valve casing 22; needle valve 23 and the stem thereof is shown in position in said casing 22 held in place and oper ated by threaded portion 24; hand wheel 25 is shown fastened to needle valve stem 23 and is for the purpose of operating said needle valve 23; packing nut 26 is shown connected to needle valve casing 22 by the threaded portion 27. This packing nut 26 is for the purpose of preventing any leakage around needle valve stem 23. Needle valve seat 28 is shown connected to needle valve casing 22 by threaded portion 29; the needle opening in said valve seat 28 is shown at 30. This needle valve seat 28 is interchangeable when a larger or smaller opening 30 is required. Combustion chamber is shown at 31 the inner opening thereof is shown at 32, the outer opening thereof is shown at 33. A plurality of air openings in combustion chamber 31 is shown at 34, adapted to concentrate and increase the combustion of the generated gas forced into said combustion chamber through needle opening 30. An eye-bolt 35 is attached to boss projection 2, adapted to engage hook 36 attached to removable generating cup 37, said generating cup 37 being filled with oil is caused to burn, which in turn causes the oil in generating chamber 12, to generate into gas, the same being drawn oif as the arrows point through needle opening 30, and caused to burn and mingle with the air in combustion chamber 31, producing an intense heat in said combustion chamber 31, said combustion chamber 31 forming the inner wall of said generating chamber 12, thereby producing a self-generating heating torch, the flame thereof being governed by needle valve 23 operated by hand wheel 25, the oil intake under pressure being governed by valve 4.

Having now fully shown and described my invention and the several improvements connected therewith, what I claim and de sire to secure by Letters Patent of the United States, -is

'1. In a self-generating heating torch the combination of a caslng having fiat walls and boss projections thereon, said boss projections being an integral part of said casing, a generating chamber in said casing, a combustion chamber in said casing, means by which fuel oil is fed to said generating chamber under pressure, means by which the amount of said fuel oil required in said generating chamber is regulated, a needle valve casing, a needle valve positioned in said casing, means by which said needle valve is operated, an interchangeable needle valve seat connected to said needle valve casing, and means by which the generated gas from a i said generating chamber is admitted to said needle valve casing and discharged through said needle valve seat into said combustion chamber, substantially as shown and de- 7 scribed.

. adapted to deliver fuel oil thereto and take generated gas therefrom, a pipe connecting coupling, adapted to be removed for the purpose of cleaning out carbon from said pipe, said needle valve casing connecting vwith said T coupling, a needle valve, and means by which the same is operated in said needle valve casing, and an interchangeable needle valve seat, said needle valve seat being connected to said needle valve casing, adapted to deliver the generated gas to said combustion chamber, substantially as shown and described.

3. In a self generating heating torch the combination of a casing having flat walls and boss projections thereon, said boss projections being an integral part thereof, a generating chamber'in said casing, an opening through each of said boss projections connecting with said generating chamber, a combustion chamber in said casing, said combustion chamber having an inner and outer opening, a plurality of air openings in said casing leading to said combustion chamber, adapted to concentrate and increase the combustion of the generated gas forced therein, means by which fuel oil is delivered to said generating chamber under pressure, means by which the generated gas is delivered from said generating chamber to said combustion chamber, a removable generating cup, and means for attaching the same to the underside of said casing, substantially as shown and described. 7

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
